Why Regular Hiking Boots Fail on Mount Everest Expeditions
On an Everest trekking trip, hiking boots work. But for the summit, you need 'Triple Boots'. These massive, insulated boots are the only thing standing between a climber and frostbite.
Triple boots have an inner liner, a shell, and an integrated gaiter. This traps heat effectively. Regular boots would freeze solid in the -40°C temperatures of the Mount Everest summit.
Climbers buy boots 1-2 sizes too big. Feet swell at altitude, and you need space for thick wool socks and toe warmers. Tight boots restrict circulation, leading to frostbite.
These boots are rigid to support crampons for climbing ice walls. They are awful for walking on trails, which is why climbers wear approach shoes until Base Camp.
Your feet are your engine. Investing in the best boots is the best insurance policy for a successful Everest expedition.
